HB Series Transformer Reverse Temperature Gradient Curing Oven

According to the process characteristics of dry-type transformers, during the initial gelation stage of epoxy resin curing, a reverse temperature gradient (bottom-to-top increasing profile) is applied inside the oven. Each temperature zone can be precisely controlled as required.

This design effectively reduces internal stress in the epoxy resin, minimizing defects such as micro-cracks and air bubbles, and ensuring that partial discharge (PD) performance meets relevant standards.

Therefore, the HB series curing oven represents an ideal upgrading solution for dry-type transformer curing processes and has been widely adopted and well recognized by customers in the transformer industry.
